It has been two months since my checkup report came back with a fasting glucose of 122 and an HbA1c of 6.5%. In that earlier post I explained what those numbers mean, but I never wrote about what I did next. The report told me to see a doctor, and before any conversation about medication started, I wanted to tackle the post-meal glucose spike on my own first. The short version: no elaborate diet. I changed the order I eat my food and I walk for 10 minutes right after meals. That was it.
Looking Again, I Was Closer to the Line Than I Thought
Fasting glucose under 100 is normal. From 100 to 125 is prediabetes, and 126 or higher is diabetes. My 122 sat near the top of the prediabetes band. HbA1c reflects your average blood sugar over the past two to three months. Under 5.7 is normal, and 6.5 is the diagnostic cutoff for diabetes. My 6.5% was sitting right on that line. It only really sank in when I laid it out in a table and saw why the report had ‘consult a doctor’ printed next to two separate lines. I had gone from 90.9kg to 75.3kg, and this part still had not followed.
What a Post-Meal Glucose Spike Actually Is
When you eat, carbohydrates break down into glucose and enter your bloodstream. If that happens fast, your blood sugar shoots up in a short window, usually peaking 30 to 60 minutes after the meal. That is the spike. The problem is that when it repeats three times a day, every day, the pancreas that produces insulin never gets a break. Fasting glucose is one morning reading. HbA1c is the accumulated average of all those spikes. So my 6.5% was really the product of three meals a day, day after day.
Same Meal, Different Order
The first thing I changed was where my chopsticks go first. Soup and side dishes first, vegetables especially, then protein like meat or fish, and rice last. A study published this year by a team at Ewha Womans University found that when vegetables were eaten first, peak post-meal glucose averaged around 125 mg/dL, but when carbohydrates came first it climbed to about 147. Measured by the total area under the glucose curve, the difference was roughly 74%. The explanation is that fiber going in first slows down how fast the carbohydrates that follow get absorbed. The food on the table is identical, only the order changes, so I could start on day one. The only cost was about five extra minutes per meal.
Ten Minutes, Starting the Moment I Put My Spoon Down
The second change was a 10-minute walk after eating. My first instinct was to wait and let the food settle, but the research I found pointed the other way: a walk that starts immediately after a meal did more to lower the glucose peak than a longer walk 30 minutes later. The logic is that your muscles use up the glucose before it has a chance to peak. So at lunch, I walk one lap around the block outside the office before going back in. At dinner, I clear the table and walk a loop around the apartment complex. On evenings when I jump rope, walking to the sports center counts. Ten minutes is small enough that I have barely missed a day in two months.
Two-Thirds of the Rice at Dinner
The third change was evening carbohydrates. Once rice moved to the end of the meal, I noticed that after vegetables and protein I often could not finish a full bowl anyway. So now I only serve two-thirds of a bowl at dinner. If I want noodles or bread, I move them to lunch. On nights out with drinks, the same order applies to the food on the table: salad or tofu first, and anything carb-heavy comes later.
What I Still Do Not Know
To be honest, I do not know how much these three changes have moved my blood sugar. I have not had a retest, and I do not own a glucose meter. There are things I can feel. The wave of sleepiness that used to hit around two in the afternoon has clearly eased, and I crave sweets less in the afternoon. But those are feelings, not numbers. Until the next checkup shows me what my fasting glucose and HbA1c actually look like, I cannot say this approach worked for me. If the numbers come back bad, I will take the doctor’s advice about medication without putting it off.
Wrapping Up
Fasting glucose 122 and HbA1c 6.5% were the numbers that stayed behind even after losing 15.6kg with jump rope. I had done plenty on the exercise side, so this time I worked on the eating side. Vegetables and protein first, rice last. Ten minutes of walking right after. Two-thirds of the rice at dinner. None of it costs money and all of it can start tonight, which is why I have been able to keep it up for two months. The next checkup report will tell me whether it worked. Either way, I plan to write down exactly what it says.
